using ggplot 's geom_pointrange() function, how change size of point , thickness of line separately? example: # make test data df <- data.frame(y=10, ymin=1, ymax=20, x=1) # store ggplot object p <- ggplot(data=df, aes(y=y, ymin=ymin, ymax=ymax, x=x)) # plot 1: big dot , thick line p + geom_pointrange(fill='blue', color='grey', shape=21, size=5) # plot 2: small dot , thin line (i want small dot , thick line or vice versa) p + geom_pointrange(fill='blue', color='grey', shape=21, lwd=1, size=5) plot 1: plot 2: can small dot thick line (or vice-versa)? a workaround might plot line , point separate geoms using geom_point , geom_errorbar . unfortunately, real application involves jittering, point , interval end in different places (unless maybe can control jittering?). i can find similar questions on ( like this ), don't directly answer one. thanks! you can use fatten in combination size : p + geom_point...

i have stored procedure called business code. code uses parallelism, multiple instances of sp running @ same time depending on conditions. there logic in sp want execute once. have table (let's call history) holds uid run , datetime when portion of code executed. here's flow: sp begin -- logic if conditions met, check if history not have entry uid 1. add entry in history current uid 2. run once code sp end the issue that, @ times, logic above still gets executed multiple times if different instances reach part @ same time. can ensure runs once? thank you! begin transaction; insert [history](uid, ...) select @uid, ... not exists ( select * [history] (holdlock) uid = @uid ); if @@rowcount = 1 begin; -- inserted, logic should run once end; commit; holdlock (equivalent running transaction under serializable , more granular) ensures no other transaction running in parallel can insert entry in history uid; tr...

hi have array using code below var selectedvalues=new array(); selectedvalues=divisi.split(","); and result is itd, ito, keuangan, sumber daya manusia but want have result "itd", "ito", "keuangan", "sumber daya manusia" do know how make that? thankyou the split return array of strings itself, if question. http://php.net/manual/en/function.split.php edit: adding more detailed answer: <?php $divisi = "itd, ito, keuangan, sumber daya manusia"; $selectedvalues = array(); $selectedvalues = split(",", $divisi); var_dump($selectedvalues) ?> the script above returns below array when run on http://phpfiddle.org/ array(4) { [0]=> string(3) "itd" [1]=> string(4) " ito" [2]=> string(9) " keuangan" [3]=> string(20) " sumber daya manusia" } as pointed out split deprecated: http://php.net/manual/en/function.split.php . please use...

i'm new c++ , writing simple program should take integers file ints , output them formatted appropriately. issue program skips 1 of values when outputting. eg (\n representing new line) "51 123\n -10\n 153 111" come out "123\n -10\n 153\n 111\n 0". tips or pointers bettering code great. here code: using namespace std; int main(int argc, char *argv[]) { size_t i; int n; int a, b, c, d, e; if (argc == 1) { while (cin >> n) { cin >> a; cin >> b; cin >> c; cin >> d; cin >> e; cout << setw(10); cout << << "\r\n"; cout << setw(10); cout << b << "\r\n"; cout << setw(10); cout << c << "\r\n"; cout << setw(10); cout << d << "\r\n"; ...

forgive ignorance. have brain fart @ moment , unable come solution. let's have list of [1, 1, 0, 0] . want calculate 4 digits binary numbers have 2 1s , 2 zeros, like: ['0110', '0011', '0101', '1100', '1010', '1001'] this works: from itertools import permutations set([''.join(x) x in list(permutations('0011', 4))]) but calculate entire permutations , discards duplicate. meaning, calculates 24 times need 6. more significant if collection [1, 1, 1, 1, 0, 0, 0, 0] . this should easy can't wrap head around it. use itertools.combinations() find possible positions ones, construct numbers using positions: def binary(length=4, ones=2): result = [] positions in combinations(range(length), ones): result.append("".join("1" if _ in positions else "0" _ in range(length))) return result result: in [9]: binary() out[9]: ['1100', '1010...

when specific architecture either little-endian or big-endian, referring whether numerical significance stored left-to-right or right-to-left in memory. question is: ordering refer how bits or ordered in byte, or how bytes ordered in memory? for example, consider number 6000=1770h=0001011101110000b . if both bits in byte , byte in memory little-endian, stored as 00001110 11101000 = 0e e8, if bits in byte big-endian, bytes in memory little-endian, stored (for it's worth, happens how visual studio seems telling me memory organized in x64 architecture) 01110000 00010111 = 70 17, if bits little-endian, bytes big-endian, stored as 11101000 00001110 = 0e e8, and finally, if bits big-endian, bytes little-endian, stored as 00010111 01110000 = 17 70 (hopefully did right.) so then, terms "little-endian" , "big-endian" refer to? terms refer ordering of bits in byte, or ordering of bytes in memory, or both? furthermore, if vs tells me that, ...
